           Summary: Unable to include arm_fp16.h on a MVE capable Cortex-M
                    target
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: azoff at gcc dot gnu.org
  Target Milestone: ---

The arm_fp16.h header file contains NEON intrinsics.
Including the header file on a MVE capable Cortex-M target should work, but now
generates about 4000 lines for errors.
